Cowell and Electra did not even make attempt to hide their affection for one another, making a lot of body contact while the photographers snapped their pictures. Cowell was holding Electra by waist as they made their way to his Rolls Royce.

They reportedly were more than just dining during the romantic dinner. "They were really into each other," a fellow diner told In Touch. "At one point, they were talking real close, and he leaned in and kissed her. They started making out!" However, a source close to Cowell told Daily Mail that it was actually a group dinner of about eight friends.

The couple got closer when they co-judged "Britain's Got Talent" in February this year. Both are single.
